Mark 9:11-13

Then they asked Jesus, “Why do the teachers of the law say that Elijah must come first?” Jesus answered, “They are right to say that Elijah must come first and make everything the way it should be. But why does the Scripture say that the Son of Man will suffer much and that people will treat him as if he were nothing? I tell you that Elijah has already come. And people did to him whatever they wanted to do, just as the Scriptures said it would happen.”
